“…However, in order to reduce the sample consumption and consequently minimize instrumental radioactivity contamination and reduce waste generation, high efficiency micronebulization might be hyphenated with ICP-MS for precise and accurate determination of ultra trace radionuclides as well as their isotopic ratios. Various low-consumption nebulisers, such as the microconcentric nebulizer (MCN) [102,103], the high efficiency nebulizer (HEN) [104][105][106][107][108][109], the direct injection nebulizer (DIN) [110][111][112], oscillating capillary nebulizer (OCN) [113,114] by using similar operation conditions for SF-ICP-MS but without application of Ar-N 2 mixed gas plasma [71]. However, the 241 Pu results had relatively large uncertainty if the intensity of signals is rather low.…”

A number of analytical methods have been developed in the past decades for environmental monitoring of plutonium (Pu) isotopes around nuclear facilities, emergency preparedness as well as for risk assessment of contaminated areas resulting from nuclear weapon tests, nuclear accidents, and the discharge of nuclear waste. This article summarizes and critically compares recently reported methods for determination of Pu isotopes in waters and environmental solid substrates, in which sample pre-treatment is imperative for separation of the target species from matrix ingredients and/or potentially interfering radionuclides prior to detection by radiometric or mass spectrometric detection techniques. Also discussed, via representative examples, is the automation of the entire analytical protocol by on-line extraction chromatography and ion exchange chromatography using flow injection (FI) or sequential injection (SI) approaches.

“…Moreover some authors have noted that because of the high solvent load, local plasma cooling is produced [15,58]. The use of these low-flow rate nebulizers as a micro-bore HPLC-ICPMS hyphenation has been described in several papers [20,24,28].…”

“…These devices have the capability to efficiently produce a fine and uniform aerosol at low sample uptake rates (e.g., 10 -100 µL min -1 ). The micronebulizers mainly used coupled to micro columns are the micro-concentric nebulizer (MCN) [57], high efficiency nebulizer (HEN) [11,14,19]; the oscillating capillary nebulizer (OCN) [58]; and the electrospray nebulizer [59].…”

Although HPLC-ICPMS has established itself as the analytical technique of choice for elemental speciation analysis, there are some remaining limitations, mainly concerning post-column dispersion effects and the degradation of the ICP stability and ionization efficiency due to organic or saline mobile phases. The application of small-bore columns in conjunction with low dead-volume interfaces proved very useful for overcoming these problems, since they can provide lower matrix load and reduced peak dispersion, along with minimization of sample size and solvent consumption, faster chromatographic separations, better resolution and sensitivity.Since, more work is expected to be reported in this area, we review recent research in the field of speciation analysis by small-bore HPLC coupled to ICPMS, with the emphasis on significant advances in methods and instrumentation, relevant applications and current limitations.
